GX500 安装​

Linux 平台快速使用 GX500 5G Dongle

需要准备​

  1. 一台 Linux 设备（OpenWRT，此处用 CUDY TR30000 演示，提前刷好官方固件）
  2. Dongle GX500 及 Type-C 数据线
  3. 可上网的 Nano-SIM 卡
  4. 一根可外网的网线，一根内网网线

安装 Nano-SIM 卡​

图片

  1. 找个塑料卡片撬开盖子
  2. SIM1 卡座轻轻的往外推，放入 Nano-SIM 卡并推回固定

接入路由器 USB 接口​

蓝色指示灯表示网络注册成功

接线说明：

  • Router-Power：路由器供电
  • USB-Dongle：接通 Dongle
  • WAN：用于给路由器上网下载驱动软件
  • LAN：OpenWRT 官方固件默认没有开启 Wi-Fi，需要用电脑接入 LAN 才可以管理（可以手动开启 Wi-Fi 后就不需要接 LAN 了）

配置 Dongle - 路由器部分​

安装配置 Dongle 上网

连接到 Linux 路由器​

图片

  1. 浏览器打开路由器管理地址 192.168.1.1，可查看路由器基本信息
  2. 使用 SSH 连接到路由器：ssh root@192.168.1.1
roy@HUAWEIMagicbookM1Pro ~ % ssh root@192.168.1.1
The authenticity of host '192.168.1.1 (192.168.1.1)' can't be established.
ED25519 key fingerprint is: SHA256:W+oPSxJkukBdzWxgtKRutIGYc5KGRfUrzS7aV9RZOek
This key is not known by any other names.
Are you sure you want to continue connecting (yes/no/[fingerprint])? yes
Warning: Permanently added '192.168.1.1' (ED25519) to the list of known hosts.
*WARNING: connection is not using a post-quantum key exchange algorithm.
*This session may be vulnerable to "store now, decrypt later" attacks.
*The server may need to be upgraded. See https://openssh.com/pq.html

配置 RM520N-GL 工作模式​

开启 minicom 管理

root@OpenWrt:~# minicom -D /dev/ttyUSB2

发送 AT 指令，回复 OK 即为成功

Welcome to minicom 2.9

OPTIONS: 
Port /dev/ttyUSB2, 07:42:02

Press CTRL-A Z for help on special keys

AT
OK

查看当前工作模式

AT+QCFG="usbnet"

预期输出：

+QCFG: "usbnet",1

切换为 ECM 模式并重启生效

AT+QCFG="usbnet",1
OK

# 重启生效
AT+CFUN=1,1

退出 minicom 终端：按 Ctrl + A，再按 X，选择 Leave Minicom? → Yes

常用模式参考：

  • AT+QCFG="usbnet",0：NDIS/QMI 模式（Windows 系统推荐）
  • AT+QCFG="usbnet",1：ECM 模式（Linux 系统较推荐）
  • AT+QCFG="usbnet",2：MBIM 模式（常用于 OpenWrt，支持较好）

常用重启方式（也可以拔掉 Dongle 重启）：

  • AT+CFUN=1,1（软件复位）
  • AT+QPOWD=1（优雅关机）
  • AT+QRST=1（硬重置）

命令配置上网​

查看是否识别到 RM520N-GL 网卡（一般为 usb0）

附加​

开启路由器 Wi-Fi 功能及配置​

注意：官方固件默认 Wi-Fi 无密码，SSID 为 OpenWrt。

# OpenWrt 默认禁止无线功能，删除禁止标志
uci del wireless.radio0.disabled
uci del wireless.radio1.disabled
uci set wireless.radio0.channel='auto'   # 频道自动
uci set wireless.radio1.channel='auto'

# 开启默认的 Wi-Fi
uci del wireless.default_radio0.disabled
uci del wireless.default_radio1.disabled
uci commit
wifi reload

自定义 Wi-Fi 密码​

自定义 Wi-Fi 信息：

  • 2.4 GHz SSID：ORBI60_2g
  • 5 GHz SSID：ORBI60
  • 密码均为：fanconn123
  • 加密方式可选：sae、psk2、sae-mixed、psk-mixed（示例中使用 psk2）
# 删除禁止标志
uci del wireless.radio0.disabled
uci del wireless.radio1.disabled
uci set wireless.radio0.channel='auto'
uci set wireless.radio1.channel='auto'

# 删除默认名为 OpenWrt 的 Wi-Fi 配置
uci del wireless.default_radio0
uci del wireless.default_radio1

# 2.4 GHz AP
uci set wireless.wifinet0=wifi-iface
uci set wireless.wifinet0.device='radio0'
uci set wireless.wifinet0.network='lan'
uci set wireless.wifinet0.mode='ap'
uci set wireless.wifinet0.ssid='ORBI60_2g'
uci set wireless.wifinet0.encryption='psk2'
uci set wireless.wifinet0.key='fanconn123'

# 5 GHz AP
uci set wireless.wifinet1=wifi-iface
uci set wireless.wifinet1.device='radio1'
uci set wireless.wifinet1.network='lan'
uci set wireless.wifinet1.mode='ap'
uci set wireless.wifinet1.ssid='ORBI60'
uci set wireless.wifinet1.encryption='psk2'
uci set wireless.wifinet1.ocv='0'
uci set wireless.wifinet1.key='fanconn123'

uci commit
